See the OpenID Provider's documentation for details on OpenID client registration. There should be a unique OpenID client for each Perceptive client application that will use OpenID connect authentication. During OpenID client registration you need to register the redirect URIs for Integration Server callbacks for each login profile you want to configure.
For example, if you are registering a login profile named hylandexperience, the endpoint you need to register for the redirect URI should be https://example.integrationserver.url/integrationserver/v1/sso/callback/hylandexperience. You must also allow at a minimum the openid scope and will also a client id and a client secret to configure a login profile in Integration Server.
See Appendix A: integrationserver.ini configuration for more information on OpenID login profile configuration options.
